![]() Does the installation cost for a tank based system differ vs a tankless system? These are the heaters I am looking at. Any input on these choices? I am also looking for input as to the savings of the tankless vs the tank based system. The house will use propane not natural gas so would be more sensitive to gas usage. Would a unit like the 45HI be able to supply a normal households hot water in our winters where the required delta T is likely 70 F? It seems like drain water heat recovery may not be cost effective in terms of payback period, but I wonder if it would make up for the lower BTU count of the 45HI.

There is a structural change associated with installing a tankless heater (a vent), and it needs to be determined pretty early on in the process - I believe it's to the tune of appx $800-$900 + HST.
Which builder are you going with? As I understand it, and someone can feel free to correct me if I'm wrong, if you get a tank with an efficiency rating over 90%, the difference in savings is negligible. Also, if you consider the potential for power failures, you'd be S.O.L with a tankless. |

if i had a builder willing to play ball and the basement elevation allowed it to fit, i would install one of these..

It turns out the house has to be tankless for energy efficiency standard of the builder so I dont have a choice aside from which tankless unit we get. I found out all the units I listed before are likely too small for Canada - now looking at:

You should check in with your builder that you can have them install your own... ours is pretty open and that wasn't an option. Last edited by JCC; 2018-10-19 at 01:04 PM. |

They are open to installing one of my choice - these are all options I am researching myself. I think Ive settled on this heater - the hot idle feature to eliminate the cold sandwich problem is pretty trick. Rheem ECOH180DVLP-2 |
